    摘要: A process of casting a scroll member for a scroll compressor including forming the scroll wrap member portions of equal height. Unequal cooling of the scroll wrap when formed causes the hardness of the wrap to vary from radially outside to radially inside. The radially outside portions of the scroll wrap are formed harder therefore reducing wear-out of the scroll member while the radially inside portions are formed softer, thereby permitting quicker run-in of the scroll set during initial startup of the scroll compressor.

    摘要: Method for forming scroll members comprising an end plate having an involute wrap rigidly affixed thereto. The end plate and involute wrap are precision formed, e.g., by casting, either as an integral element or as two separate elements and then the scroll member is broached to the desired dimensional accuracy and finish. Push broaching is accomplished with an involute broaching tool which has a single terminating cutting edge on one or both sides of an involute blade cutter.

    摘要: Provided is an internal gear pump integrally provided with a plain bearing requiring fewer machining steps, allowing inexpensive manufacture, and offering a highly stable seizing property. An internal gear pump (1) comprises: a trochoid (4), in which an inner rotor (3) having a plurality of outer teeth is eccentrically and rotatably accommodated in an outer rotor (2) having a plurality of inner teeth, the outer teeth meshing with the inner teeth, and in which a suction-side chamber for suctioning liquid and a discharge-side chamber for discharging the liquid that has been suctioned into the suction-side chamber are formed between the inner teeth and outer teeth; a drive shaft (9) fixed to the inner rotor (3); a casing (5) in which is formed a recess (5a) for accommodating the trochoid (4); and a cover (6) for closing off the recess (5a) of the casing (5). The cover (6) has a plain bearing part (11) for rotatably supporting the drive shaft (9), and the plain bearing part (11) is formed by injection-molding a thermoplastic resin composition directly onto the cover (6).
